The purpose of this study was to assess the provided home health care services and to evaluate the patient's satisfaction level of received home health care services. Well trained two home health care nurses interviewed with 138 respondents who received home health care by Keimyung University Hospital from January 1st to August 31st 1999. The results were summarized as follows : 1) Among 138 respondents, $55.8\%$ were mail and $44.2\%$ were female and $70.3\%$ of them were over sixty years old. Respondents main family care givers were spouse$(53.6\%)$, daughters and sons$(36.2\%)$ and parents$(7.2\%)$. 2) $60.2\%$ of cancer patients received home health care services, $23.3\%$ of cerebral­cardiovascular patients, $7.5\%$ of endocrine disorder patients, $2.3\%$ of those who have indwelling foley catheter patients, $1.5\%$ of those who have respiratory problems and others$(5.2\%)$. 3) $88.1\%$ of respondents were satisfied with the number of home visits they received. $50.5\%$ of respondents' were received 1 to 3 times of home visits by home health care nurse per month. $48.6\%$ of respondents answered they were introduced by attending doctors or nurses to home health care services. $55.8\%$ of respondents answered registration to home health care services was simple and easy. $97.4\%$ of respondents answered home health care payment system was adequate. $64.9\%$ of respondents answered the cost of home health care per visit was adequate and comfortable. 4) Health education, counselling, physical assessment was provided to most of the patients. Those who suffered with cerebral-cardiovascular disease was needed hands on direct care most of all. The least home health care service provided was medication. 5) The satisfaction measurement tool was composed with 13 items and 3 score scale. The mean score of satisfaction on provided home health care services was 2.67 out of 3. Among 13 items. 'home health care service was kind enough' was highest(2.84). 'nurse use precise word to understand and communicate'. 'nurse gave home visiting notice ahead of time and kept the home visiting promise on time' was 2.83. 'whenever I need home health care nurse I can give a call and meet the nurse' was lowest 2.41. Special Home Health care programs such as comprehensive hospice care programs for elders over sixty years old should be organized. Adequate and standardized home health care payment system should be developed as soon as possible. In korean family situation. when family members are getting sick and stay at home. family members were taking care of the patients. special program such as counselling family members are needed.

Objective: This experiment was to evaluate the effects of the dietary energy levels on the physiological parameters and reproductive performance during gestation over three parities in sows. Methods: A total of 52 F1 gilts ($Yorkshire{\times}Landrace$) were allotted to one of four dietary treatments using a completely randomized design. The treatments contained 3,100, 3,200, 3,300, or 3,400 kcal of metabolizable energy (ME)/kg diet but feed was provided at 2.0, 2.2, and 2.4 kg/d in the first, second and third parity, respectively. Results: The body weight and body weight gain during gestation increased as the dietary energy level increased (p<0.05, and p<0.01) in the first parity. In the second parity, the body weight of sows was the lowest (p<0.05) when 3,100 kcal of ME/kg treatment diet was provided. The body weight was higher as the dietary energy level increased (p<0.05) during the gestation period in the third parity. During lactation, the voluntary feed intake of lactating sows tended to decrease when gilts were fed higher energy treatment diet (p = 0.08) and the body weight, body weight gain were increased by dietary energy level during gestation (p<0.05). Backfat thickness was not affected by dietary treatment during the gestation period in three parities, interestingly backfat change from breeding to d 110 of gestation was higher as the dietary energy level increased at the first parity (p<0.05). When gilts were fed 3,400 kcal of ME/kg treatment diet a higher number of weaning piglets was observed in the first parity (p<0.05). The highest culling rate (69%) was seen when gestating sows were fed 3,100 kcal/kg ME treatment diet during three parities. Conclusion: In conclusion, the adequate energy intake of gestating sows should be 6,400 or 6,600 kcal of ME/d, 7,040 or 7,260 kcal of ME/d, and 7,680 or 7,920 kcal of ME/d for parity 1, 2, and 3, respectively.

The noise and vibration generated by the subway rolling stocks operated along the Seoul Subway Line No.1, 2, 3, and 4 lead to a controversy of pollution problem especially in residential areas. However, there is no data or guide to define the damage or provide adequate protection against such pollutions. The field measurements were made to characterize the noise attenuation due to distance, noise level distribution around the subway track of the aboveground and underground parts of each Line. The assessment criteria and methods are considered in addition to the practical available noise control methods. The noise level measured at Line No. 1 and 3 are less than 60 dB(A) with no pollution problem. Only a part of the aboveground section of Line No.2 and 4 indicates severe noise pollution. The effective boundary of these areas exposed to 70dB (A) noise are within 50m from the track centerline of No.2 line and 25m of No.4 line. The residents file a strong complaints whenever the noise level exceeds the 80dB (A) , and an occasional complaints between 70 to 80 dB(A). The distribution of high level noise of 80 dB(A) occurs within 25m from the track centerline of the overbridge, 12.5m of the short steel bridge, and about loom of the long steel bridge such as Dangsan Bridge. The intermediate noise level of 70 to 80 dB(A) is recorded within 50m from the overbridge, U-type retaining structure, and short steel structure, and 280m from the long steel bridge. The results presented in this paper can be used to understand the characteristics of the noise pollution along the Seoul Subway now In operation, and used as a guide to improve the existing noise pollution problems.

A total of 1,440 White Leghorn pullets hatched in summer and winter, aged 20 to 72 weeks were fed 9 rations differing in dietary protein (13, 15 and 17%) and energy (2,500, 2,700 and 2,900 kcal/kg) levels for a period of 52 weeks in order to evaluate the optimum dietary energy and protein levels for laying hens. As metabolizable energy level increased from 2,500 to 2,900 kcal/kg of feed egg production, daily feed and protein intake and egg shell quality decreased, but reverse was true for the daily energy intake, energy requirement and feed cost per kg egg, body weight gain, nutrients utilizability and abdominal fat accumulation, Egg weight, viability and egg yolk Pigmentation were not affected by the dietary energy level. On the other hand, as dietary protein level increased from 13 to 17%, egg production, egg weight, daily protein intake, protein requirement per kg egg and body weight gain icreased, but daily feed and energy intake, feed and energy requirement per kg egg, egg yolk pigmentation and dry matter utilizability decreased, and no significant difference in the feed cost per kg egg, viability and egg shell quality was observed among dietary protein levels. However: the hens fed 15% and 17% Protein diets did not show significant differences in egg production, egg weight and body weight gain. For the entire laying period of 52 weeks, metabolizable energy level of 2,500 kcal/kg of feed and 15% dietary protein level were considered to be adequate to support the optimum productivity.

Objectives: This study is to offer basic data to understand the relationships between mental health, level of depression, and internet addiction of high school students in farming communities for developing a mental health management program for adolescents. Methods: The survey was carried out on a convenience sample of 299 high school students in farming communities during May of 2008. Data analysis procedure included $X^2$-test, t-test, Pearson correlation among Adolescent Mental Health & Problem-behavior Screening Questionnaire (AMPQ), Children's Depression Inventory (CDI), and Scales of Internet addiction (K-scales). Results: First, the level of mental health according to the AMPQ for subjects from this study showed problematic behavior was lower when compared to other researches. There were statistically significant differences according to the school type for externalization problems and overall problematic behavior. Based on gender, it was even more problematic for male students in regards to externalization problems. Secondly, the level of depression was relatively low : 5.1% for potential risk and 0.3% for high risk. Thirdly, a total of 96.9% were considered normal for Internet addition levels. 1.7% for potential risk, 1.4% for high risk; however, there was no statistically significant difference between each variable. Fourthly, there was a strong relationship between subjects AMPQ, level of depression and Internet addiction. As depression worsens, Internet addiction also becomes stronger. Conclusion: There is a need for awareness of the mental health of adolescents and precautionary measures, the development of a program for early treatment, adequate management, and decisions on the direction of treatment.

Purpose: To determine the proper reference step wedge for digital Cu-Equivalent Image analyzing systems for measurement of bone density. Meterials and Methods : Radiograms of lumbar vertebrae phantom (1g/㎠) with 3 test copper step wedges of 0.03, 0.05 and, 0.1 mm thickness unit were taken and analyzed using NIH image software on a Macintosh personal computer. Measured densities of the lumbar areas in the Cu-Equivalent images made by utilizing 3 different copper stepwedges were compared with a known bone density. Results: The values of r2 for all copper equivalent images were over 0.99. The mean Cu-Eq value of lumbar in copper equivalent image made by a 0.1 mm copper stepwedge was 0.22 ± 0.06 mm and converted to hydroxyapatite density of 1.03 g/㎠. The stepwedges of 0.03 and 0.05 mm produced results having higher values than the actual known bone density. They did not show the blue and green color level that appeared in lumbar on color enhanced image. Conclusion : A copper stepwedge of adequate thickness and range of steps which can express the range of density of bone being measured should be used.

In recent years a great deal of information has accumulated for livestock on vitamin. function, metabolism and supplemental needs. The role of the antioxidant "vitamins" (carotenoids, vitamin E and vitamin C) in immunity and health of livestock has been a fruitful area of research. These nutrients play important roles in animal health by inactivating harmful free radicals produced through normal cellular activity and from various stressors. Both in vitro and in vivo studies showed that these antioxidant vitamins generally enhance different aspects of cellular and noncellular immunity. A compromised immune system will result in reduced animal production efficiency through increased susceptibility to diseases, thereby leading to increased animal morbidity and mortality. Vitamin E has been shown to increase performance of feedlot cattle and to increase immune response for ruminant health, including being beneficial for mastitis control. Vitamin E given to finishing cattle at higher than National Research Council (NRC) requirements dramatically maintained the red color (oxymyoglobin) compared with the oxidized metmyoglobin of beef. Under commercial livestock and poultry production conditions, vitamin allowances higher than NRC requirements may be needed to allow optimum performance. Generally, the optimum vitamin supplementation level is the quantity that achieves the best growth rate, feed utilization, health (including immune competency), and provides adequate body reserves.

In the case of seismic-resistant composite dual moment resisting and eccentrically braced frames, the current design practice is to avoid the disposition of shear connectors in the expected plastic zones, and consequently to consider a symmetric moment or shear plastic hinges, which occur only in the steel beam or link. Even without connectors, the real behavior of the hinge may be different from the symmetric assumption since the reinforced concrete slab is connected to the steel element close to the hinge locations, and also due to contact friction between the concrete slab and the steel element. At a larger level, the structural response in the case of important seismic motions depends directly on the elasto-plastic behavior of elements and hinges. The numerical investigation presented in this study summarizes the results of elasto-plastic analyses of several steel frames, considering the interaction of the steel beam with the concrete slab. Several parameters, such as the inter-story drift, plastic rotation requirements and behavior factors q were monitored. In order to obtain accurate results, adequate models of plastic hinges are proposed for both the composite short link and composite reduced beam sections.

A 49-year-old man with drowsy mentality was diagnosed with acute type A aortic dissection; he underwent an emergency operation. When selective antegrade cerebral perfusion was initiated, the right regional cerebral oxygen saturation ($rSO_2$) decreased as compared to the left one. Adequate blood flow was perfused through the branch of the artificial graft, after distal anastomosis, but the right $rSO_2$ did not recover. Angiography revealed another intimal tear on the right common carotid artery. A stent was then inserted. The right $rSO_2$ promptly increased to the same level as that of the left one. The patient was discharged without any neurologic complications.

The purpose of this study was to provide basic references in order to improve the quality of military foodservice by investigating the eating behavior, preferred items for improvement and foodservice satisfaction of male military personnel in Backrung do. A total of 213 male military personnel (66 sergeants, 44 corporals, 80 privates first class and 27 privates third class) responded to a survey questionnaire. Frequencies, t tests, analysis of variance, and Cronbach's alpha, were carried out by SPSS Win V.18.0. The results of the study were as follows. The satisfaction level of military foodservice was slightly below 3 out of 5 points, and Korean cuisine was the favorite food. Military male personnel preferred frying and stewing as their favorite cooking methods. Sixty-six percent of subjects answered that their favorite principal ingredients were meat and fish. Therefore, as young soldiers' taste preferences were westernized, proper nutrition education programs for good health are needed. Further, the current military dining environment should be changed into a quiet and neat atmosphere, with clean dishes, nutritious meal items, and quick and proper serving methods, etc. Based on the results above, military authorities should develop an adequate menu for the male military personnel at Backrung do military base that includes a variety of foods, and cooking methods.
